REAR SIDE WINDOW ~EMISTER
BACKGROUND OF THE INVENTION
1. Field of the Invention The present invention relates in general to a side window demister or defroster for an automotive vehicle having a center pillar and a rear side window behind the center pillar, and particularly to a rear side window demister for preventing condensation on the interior of the rear side window.
REAR SIDE WINDOW ~EMISTER
BACKGROUND OF THE INVENTION
1. Field of the Invention The present invention relates in general to a side window demister or defroster for an automotive vehicle having a center pillar and a rear side window behind the center pillar, and particularly to a rear side window demister for preventing condensation on the interior of the rear side window.
2. Description of the Prior Art Fig. 1 is a horizontal section of a typical center pillar and pillar garnish assembly 10 placed between a front door window 12 and a rear door window 14, i.e., a front side window and a rear side window. The center pillar is generally indicated at 16 and formed from inner and outer panels 18 and 20 which are joined together to constitute a closed configuration or a box-like horizontal section. The center pillar '16 has front and rear end flanges 16a and 16b where the inner and outer panels 18 and 20 are spot-welded or otherwise secured together. Though not shown, the upper and lower ends of the center pillar 10 are respectively secured to a roof side rail and a side sill to serve as a highly rigid structural mem-er of a vehic ~ y.
_ 1 _ The pillar garnish is indicated at 22 and adapted to cover the center pillar 16 in order to attain a refined appearance of a passenger compartment 24. The pillar garnish 22 is hooked at the front and rear~hook-shaped ends 22a and 22b on to the front and rear end flanges 16a and 16b of the center pillar 16 and also secured at an intermediate portion between the front and rear hook-shaped ends 16a and 16b to the center pillar 16 by means of suitable fasteners 26.
The automotive vehicle with such a center pillar and pillar garnish, however, encounters a drawback of poor rear side visibility. That is, in winter or in a rainy season, the front and rear side windows 12 and 14 are likely to be clouded up due to condensation lS on the interior thereof. In order to prevent such condensation, recently produced cars are equipped with a side demister which includes a demister nozzle located at a lateral end of an instrument panel or on a front pillar. When the side demister is used, hot, dry air directed from a heat source is forced aKainst the front side window 12 to remove mi~t or moisture or the like as well as to prevent condensationO The hot, dry air also flows rearwardly along the front side window 12, i.e., toward the center pillar 16. In this instance9 since the center pillar 16 and the pillar garnish 22 are located more interiorly of the passenger compartment 24 as compared with the ~ront and rear side windows 12 and 14 9 the hot, dry air having reached the center pillar 16 is caused to change its direction of flow as indicated by arrows in the drawing and flow away inwardly of the passenger compartment 24. For this reason, the hot, dry ain discharged from the side demister cannot reach or blow against the rear side window 14, making it impossible to remove mist or moisture or the like on the interior of the rear side window 14 as well as to prevent condensation on same and there~ore resulting in poor rear side visibility through the rear side window 14.
SUMMARY OF THE INVENTION
In accordance with the present invention, there is provided a rear side window demister for an autornotive vehicle having a side demister nozzle installed on or adjacent a front pillar. The rear side window demister comprises a center pillar located between a front side window and a rear side window, and a pillar garnish attached to the center pillar for preverting same from view.
The above structure substantially follows the conventional fashion. In accordance with the present invention, the pillar garnish is adapted to cooperate

SUMMARY OF THE INVENTION
In accordance with the present invention, there is provided a rear side window demister for an autornotive vehicle having a side demister nozzle installed on or adjacent a front pillar. The rear side window demister comprises a center pillar located between a front side window and a rear side window, and a pillar garnish attached to the center pillar for preverting same from view.
The above structure substantially follows the conventional fashion. In accordance with the present invention, the pillar garnish is adapted to cooperate
-3 with the center pillar to defi.ne therebetween a space which serves as a demister duct for conveying hot, dry air directed from the side demister nozzle to the rear side window.
With this structure, the hot, dry air having reached the center pillar is effectively conveyed to the rear side window to prevent condensation, thereby providing an improved rear side visibility through the rear side window.
It is accordingly an object of the present invention to provide a rear side window demister for an automotive vehicle which can provide an improved rear side visibilityO
It i~ a further object of the present invention to provide a rear side window demister of the above mentioned character which is attained through a slight modification of a center pillar and pillar garnish assembly.
It is a further object of the present invention to provide a rear side window demistor of the above ~ mentioned character which is adap-ted to effectively utilize hot, dry air blown from a nozzle of a side demi~tor which is standard-equipped in many recently produced cars.
